Description
Description
The PIC12CXXX family of devices adds a new twist to the 8-bit microcontroller market by introducing for the first time fully functional microcontrollers in an eight pin package. These parts are not stripped down versions of their larger brethren, they add features in a package smaller than available ever before for microcontrollers. Using the familiar 12-bit opcode width of the PIC16C5X family with the same TMR0 module, Device Reset Timer, and WatchDog Timer (WDT), the PIC12C5XX family adds an internal 4MHz oscillator main clock, serial programming, wake-up on change, user selectable weak pullups, and multiplexing of the MCLR, T0CKI, OSC1, and OSC2 pins. This combination of familiar and new features in a compact package gives the designer unprecedented flexibility to produce designs which are much cheaper and smaller than ever before possible, and allows the replacement of even mundane devices like timers and discrete components economically. This reference note describes an application where the use of a microcontroller was not previously economically feasible for any but the highest end products: lamp dimming.
